I’ve read about Homeland Security and the FBI monitoring the Internet for discussions of zombies, since you can discuss survivalism, military tactics and evasion tactics under that guise.
I can also see how ham radio gets a thumbs up post-Apocalypse (of any type).
* Not easily monitored by the government like your cell phone conversations via monitoring software or internet activities.
* Works even after an EMP attack if you put it in properly shielded storage.
* It’s an existing network of emergency communications volunteers today, so joining with hams gives you a communication and support network immediately.
* I know lots of hams who were preppers for nuclear war, so you can find modern day preppers of the older generation, just gaining new ones for new threats today.
ham radio makes sense as part of an infrastructure for survivalists after the fall, that is for sure.
